The Zhizhong Resonance-Free Vibratory Hammer EP550B Empowers the Fodu Project of CCCC Third Harbour Consultants Co., Ltd. Once Again

——Build a solid foundation for world-class ports with stability and strength

In the waters of Liuheng Island in Zhoushan, Zhejiang, the tides are surging and the wind and waves are incessant. The first phase of the construction of the Fodu Operation Area in the Liuheng Port Area of Ningbo Zhoushan Port is currently underway, which is a national key port hub project.

At the construction site constructed by CCCC Third Harbor Engineering Co., Ltd., the Shanghai Zhenzhong EP550B resonance free large eccentric moment vibration hammer has become one of the core equipment for gravel pile foundation treatment with its excellent performance of stability, high efficiency, and energy saving, laying a solid foundation for the project at the port.

01.「Efficiency Breakthrough Under Complex Marine Conditions」

The first phase of the Fodu operation area project plans to construct two 200000 ton container berths, with a total land area of approximately 931400 square meters, of which over 80% is for foundation treatment.

The geological conditions of the project are complex, with a local silt layer thickness of over 40 meters, a pile diameter of 1 meter, and a maximum pile sinking depth of about 40 meters. This places extremely high demands on the equipment's ability to penetrate the soil and the stability of continuous operation.

Under this working condition, EP550B achieves rapid pile sinking with large eccentricity, strong vibration impulse, and stable product performance. At present, there are 4 EP550B devices operating synchronously. Whether it is pile sinking or pile pulling, they can maintain efficient and stable operation in long-term and high-frequency working environments, providing reliable verification for subsequent large-scale foundation treatment.

02.「Steady Power for Precision Foundation」

EP550B is designed specifically for gravel pile and compacted sand pile construction methods, with multiple key advantages:

Resonance free start-up: The eccentric torque stepless adjustable technology ensures that there is no resonance during the start-up and shutdown processes, avoiding equipment and pile frame damage caused by resonance and ensuring construction safety.

Powerful vibration impulse: With a large eccentric moment and a large vibration impulse output, it can easily overcome end resistance and effectively sink large-diameter and ultra deep gravel piles up to 40 meters in a fast manner.

Intelligent monitoring: an expandable information system that records pile position, pile depth, pile diameter, sinking and pulling time, average operating speed, gravel volume, and pile pulling force, achieving visualization and intelligence of the entire operation process.

Balancing energy conservation and durability: The dual output shaft vibration resistant variable frequency motor, combined with an external circulating cooling system, reduces heat generation and energy consumption, and supports long-term continuous construction.

At present, the information system of on-site equipment is gradually being improved, and in the future, real-time display of construction parameters and data retention will be achieved, providing scientific basis for standardized construction of projects.

03.「Chinese Manufacturing」

The Fodu project is an important project for Zhejiang Province to promote the "Strong Port Strategy" and the "Ningbo Zhoushan Integration" strategy.

The stable performance of EP550B provides strong support for Ningbo Zhoushan Port, a world-class port hub.

From every start of the vibrating hammer to every line of record in data-driven construction, it is a true footnote to 'Made in China' - safety, strength, and reliability.

This is not only Zhenzhong's product belief, but also the confidence for Chinese equipment to go global.

Note: The above are some models. Our company provides a complete range of EP series and KLV series vibration hammers specifically designed for gravel piles to meet different working conditions.
